In the past ten years nearly 67% of the fatal boating accidents in Idaho were the result of victims involuntarily entering the water from small boats. The average water temperature of Idaho’s water is 52 degrees, even during the summer! Wearing a life jacket can greatly increase your risk of surviving a cold water immersion situation.
4 Dangerous Categories of Cold Water Immersion
Cold Shock – Initial entry – 5 minutes:
- Involuntary gasping, hyperventilation, & vertigo
Swim Failure – 5 – 30 minutes:
- Even the best swimmers cannot function in cold water
- Muscles, nerves, arms & legs cool quickly
- Manual dexterity, grip strength & movement speed drop 60-80%
Hypothermia – 30 minutes or more:
- Depends on water temperature, clothing, body type & behavior
- Heat loss is 25 times faster in the water
Post Immersion Collapse:
- Heart problems can develop as cold blood is released into the body core from the extremities
To increase your chances of surviving cold water immersion, always wear your life jacket.
